3 | ||
c5e8580e | 4 | Changes between 0.9.6 and 0.9.7 [xx XXX 2000] |
a43cf9fa | 5 | |
c1081080 BM |
6 | *) Implement ssl23_peek (analogous to ssl23_read), which previously |
7 | did not exist. | |
8 | [Bodo Moeller] | |
9 | ||
bb62a8b0 BM |
10 | *) Replace rdtsc with _emit statements for VC++ version 5. |
11 | [Jeremy Cooper <jeremy@baymoo.org>] | |
bd9e2e4c | 12 | |
c62b26fd BM |
13 | *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them |
14 | in <openssl/bn.h>. Also further increase BN_CTX_NUM to 24. | |
15 | [Bodo Moeller] | |
16 | ||
2dc769a1 DSH |
17 | *) Modify EVP_Digest*() routines so they now return values. Although the |
18 | internal software routines can never fail additional hardware versions | |
19 | might. | |
20 | [Steve Henson] | |
21 | ||
5277d7cb BM |
22 | *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: |
23 | ||
24 | Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 | |
25 | (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. | |
26 | ||
27 | ASN1 error codes | |
28 | ERR_R_NESTED_ASN1_ERROR | |
29 | ... | |
30 | ERR_R_MISSING_ASN1_EOS | |
31 | were 4 .. 9, conflicting with | |
32 | ERR_LIB_RSA (= ERR_R_RSA_LIB) | |
33 | ... | |
34 | ERR_LIB_PEM (= ERR_R_PEM_LIB). | |
35 | They are now 58 .. 63 (i.e., just below ERR_R_FATAL). | |
36 | ||
37 | Add new error code 'ERR_R_INTERNAL_ERROR'. | |
38 | [Bodo Moeller] | |
39 | ||
40 | *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock | |
41 | suffices. | |
42 | [Bodo Moeller] | |
43 | ||
bad40585 BM |
44 | *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This |
45 | sets the subject name for a new request or supersedes the | |
46 | subject name in a given request. Formats that can be parsed are | |
47 | 'CN=Some Name, OU=myOU, C=IT' | |
48 | and | |
49 | 'CN=Some Name/OU=myOU/C=IT'. | |
50 | ||
51 | Add options '-batch' and '-verbose' to 'openssl req'. | |
52 | [Massimiliano Pala <madwolf@hackmasters.net>] | |
53 | ||
757a8b46 RL |
54 | *) Make it possible to reuse SSLv2 sessions. |
55 | [Richard Levitte] | |
56 | ||
62dc5aad RL |
57 | *) Introduce the possibility to access global variables through |
58 | functions on platform were that's the best way to handle exporting | |
59 | global variables in shared libraries. To enable this functionality, | |
60 | one must configure with "EXPORT_VAR_AS_FN" or defined the C macro | |
61 | "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter | |
62 | is normally done by Configure or something similar). | |
63 | ||
64 | To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL | |
65 | in the source file (foo.c) like this: | |
66 | ||
67 | OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; | |
68 | OPENSSL_IMPLEMENT_GLOBAL(double,bar); | |
69 | ||
70 | To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL | |
71 | and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: | |
72 | ||
73 | OPENSSL_DECLARE_GLOBAL(int,foo); | |
74 | #define foo OPENSSL_GLOBAL_REF(foo) | |
75 | OPENSSL_DECLARE_GLOBAL(double,bar); | |
76 | #define bar OPENSSL_GLOBAL_REF(bar) | |
77 | ||
78 | The #defines are very important, and therefore so is including the | |
79 | header file everywere where the defined globals are used. | |
80 | ||
81 | The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition | |
82 | of ASN.1 items, but that structure is a bt different. | |
83 | ||
84 | The largest change is in util/mkdef.pl which has been enhanced with | |
85 | better and easier to understand logic to choose which symbols should | |
86 | go into the Windows .def files as well as a number of fixes and code | |
87 | cleanup (among others, algorithm keywords are now sorted | |
88 | lexicographically to avoid constant rewrites). | |
89 | [Richard Levitte] | |
90 | ||
f23478c3 DSH |
91 | *) In copy_email() check for >= 0 as a return value for |
92 | X509_NAME_get_index_by_NID() since 0 is a valid index. | |
93 | [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>] | |
94 | ||
3d2e469c DSH |
95 | *) In BN_div() keep a copy of the sign of 'num' before writing the |
96 | result to 'rm' because if rm==num the value will be overwritten | |
97 | and produce the wrong result if 'num' is negative: this caused | |
98 | problems with BN_mod() and BN_nnmod(). | |
99 | [Steve Henson] | |
100 | ||
fafc7f98 DSH |
101 | *) Function OCSP_request_verify(). This checks the signature on an |
102 | OCSP request and verifies the signer certificate. The signer | |
103 | certificate is just checked for a generic purpose and OCSP request | |
104 | trust settings. | |
105 | [Steve Henson] | |
106 | ||
f1965221 DSH |
107 | *) Add OCSP_check_validity() function to check the validity of OCSP |
108 | responses. OCSP responses are prepared in real time and may only | |
109 | be a few seconds old. Simply checking that the current time lies | |
110 | between thisUpdate and nextUpdate max reject otherwise valid responses | |
111 | caused by either OCSP responder or client clock innacuracy. Instead | |
112 | we allow thisUpdate and nextUpdate to fall within a certain period of | |
113 | the current time. The age of the response can also optionally be | |
114 | checked. Two new options -validity_period and -status_age added to | |
115 | ocsp utility. | |
116 | [Steve Henson] | |
117 | ||
4ff18c8c DSH |
118 | *) If signature or public key algorithm is unrecognized print out its |
119 | OID rather that just UNKOWN. | |
120 | [Steve Henson] | |
121 | ||
db4a4659 DSH |
122 | *) Avoid coredump with unsupported or invalid public keys by checking if |
123 | X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when | |
124 | PKCS7_verify() fails with non detached data. | |
125 | [Steve Henson] | |
126 | ||
d7c06e9e DSH |
127 | *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and |
128 | OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate | |
129 | ID to be generated from the issuer certificate alone which can then be | |
130 | passed to OCSP_id_issuer_cmp(). | |
131 | [Steve Henson] | |
132 | ||
386828d0 DSH |
133 | *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new |
134 | ASN1 modules to export functions returning ASN1_ITEM pointers | |
135 | instead of the ASN1_ITEM structures themselves. This adds several | |
136 | new macros which allow the underlying ASN1 function/structure to | |
137 | be accessed transparently. As a result code should not use ASN1_ITEM | |
138 | references directly (such as &X509_it) but instead use the relevant | |
139 | macros (such as ASN1_ITEM_rptr(X509)). This option is to allow | |
140 | use of the new ASN1 code on platforms where exporting structures | |
141 | is problematical (for example in shared libraries) but exporting | |
142 | functions returning pointers to structures is not. | |
143 | [Steve Henson] | |
144 | ||
fa2b8db4 GT |
145 | *) Add support for overriding the generation of SSL/TLS session IDs. |
146 | These callbacks can be registered either in an SSL_CTX or per SSL. | |
147 | The purpose of this is to allow applications to control, if they wish, | |
148 | the arbitrary values chosen for use as session IDs, particularly as it | |
149 | can be useful for session caching in multiple-server environments. A | |
150 | command-line switch for testing this (and any client code that wishes | |
151 | to use such a feature) has been added to "s_server". | |
152 | [Geoff Thorpe, Lutz Jaenicke] | |
153 | ||
d399fdf8 RL |
154 | *) Modify mkdef.pl to recognise and parse prprocessor conditionals |
155 | of the form '#if defined(...) || defined(...) || ...' and | |
156 | '#if !defined(...) && !defined(...) && ...'. This also avoids | |
157 | the growing number of special cases it was previously handling. | |
158 | [Richard Levitte] | |
159 | ||
5003a61b UM |
160 | *) Don't use getenv in library functions when run as setuid/setgid. |
161 | New function OPENSSL_issetugid(). | |
162 | [Ulf Moeller] | |
163 | ||
cf1b7d96 RL |
164 | *) Make all configuration macros available for application by making |
165 | sure they are available in opensslconf.h, by giving them names starting | |
166 | with "OPENSSL_" to avoid conflicts with other packages and by making | |
167 | sure e_os2.h will cover all platform-specific cases together with | |
168 | opensslconf.h. | |
2affbab9 RL |
169 | Additionally, it is now possible to define configuration/platform- |
170 | specific names (called "system identities"). In the C code, these | |
171 | are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another | |
172 | macro with the name beginning with "OPENSSL_SYS_", which is determined | |
173 | from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on | |
174 | what is available. | |
cf1b7d96 RL |
175 | [Richard Levitte] |
176 | ||
acba75c5 DSH |
177 | *) New option -set_serial to 'req' and 'x509' this allows the serial |
178 | number to use to be specified on the command line. Previously self | |
179 | signed certificates were hard coded with serial number 0 and the | |
180 | CA options of 'x509' had to use a serial number in a file which was | |
181 | auto incremented. | |
182 | [Steve Henson] | |
183 | ||
934397ec BM |
184 | *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c) |
185 | due to incorrect handling of multi-threading: | |
186 | ||
187 | 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl(). | |
188 | ||
189 | 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on(). | |
190 | ||
191 | 3. Count how many times MemCheck_off() has been called so that | |
192 | nested use can be treated correctly. This also avoids | |
193 | inband-signalling in the previous code (which relied on the | |
194 | assumption that thread ID 0 is impossible). | |
195 | [Bodo Moeller] | |
196 | ||
a6b7ffdd DSH |
197 | *) New options to 'ca' utility to support V2 CRL entry extensions. |
198 | Currently CRL reason, invalidity date and hold instruction are | |
199 | supported. Add new CRL extensions to V3 code and some new objects. | |
200 | [Steve Henson] | |
201 | ||
f30d34f3 LJ |
202 | *) Add "-rand" option also to s_client and s_server. |
203 | [Lutz Jaenicke] | |
204 | ||
f2e5ca84 DSH |
205 | *) New function EVP_CIPHER_CTX_set_padding() this is used to |
206 | disable standard block padding (aka PKCS#5 padding) in the EVP | |
207 | API, which was previously mandatory. This means that the data is | |
208 | not padded in any way and so the total length much be a multiple | |
209 | of the block size, otherwise an error occurs. | |
210 | [Steve Henson] | |
211 | ||
cdc7b8cc DSH |
212 | *) Initial (incomplete) OCSP SSL support. |
213 | [Steve Henson] | |
214 | ||
720235ee UM |
215 | *) Fix CPU detection on Irix 6.x. |
216 | [Kurt Hockenbury <khockenb@stevens-tech.edu> and | |
217 | "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
218 | ||
67c18019 DSH |
219 | *) New function OCSP_parse_url(). This splits up a URL into its host, |
220 | port and path components: primarily to parse OCSP URLs. New -url | |
221 | option to ocsp utility. | |
222 | [Steve Henson] | |
223 | ||
46a58ab9 DSH |
224 | *) New nonce behavior. The return value of OCSP_check_nonce() now |
225 | reflects the various checks performed. Applications can decide | |
226 | whether to tolerate certain situations such as an absent nonce | |
227 | in a response when one was present in a request: the ocsp application | |
228 | just prints out a warning. New function OCSP_add1_basic_nonce() | |
229 | this is to allow responders to include a nonce in a response even if | |
230 | the request is nonce-less. | |
231 | [Steve Henson] | |
232 | ||
94fcd013 DSH |
233 | *) Use the cached encoding of an X509_NAME structure rather than |
234 | copying it. This is apparently the reason for the libsafe "errors" | |
235 | but the code is actually correct. | |
236 | [Steve Henson] | |
237 | ||
620cea37 BM |
238 | *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are |
239 | skipped when using openssl x509 multiple times on a single input file, | |
240 | e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs". | |
241 | [Bodo Moeller] | |
242 | ||
ccb08f98 DSH |
243 | *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string() |
244 | set string type: to handle setting ASN1_TIME structures. Fix ca | |
245 | utility to correctly initialize revocation date of CRLs. | |
246 | [Steve Henson] | |
247 | ||
836f9960 LJ |
248 | *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override |
249 | the clients preferred ciphersuites and rather use its own preferences. | |
250 | Should help to work around M$ SGC (Server Gated Cryptography) bug in | |
251 | Internet Explorer by ensuring unchanged hash method during stepup. | |
252 | [Lutz Jaenicke] | |
253 | ||
c47c6196 DSH |
254 | *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael |
255 | to aes and add a new 'exist' option to print out symbols that don't | |
256 | appear to exist. | |
257 | [Steve Henson] | |
258 | ||
8c950429 DSH |
259 | *) Additional options to ocsp utility to allow flags to be set and |
260 | additional certificates supplied. | |
261 | [Steve Henson] | |
262 | ||
9235adbf RL |
263 | *) Add the option -VAfile to 'openssl ocsp', so the user can give the |
264 | OCSP client a number of certificate to only verify the response | |
265 | signature against. | |
266 | [Richard Levitte] | |
267 | ||
57e7d3ce UM |
268 | *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent |
269 | Bleichenbacher's DSA attack. | |
f2bc6684 BM |
270 | Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits |
271 | to be set and top=0 forces the highest bit to be set; top=-1 is new | |
272 | and leaves the highest bit random. | |
35ed8cb8 | 273 | [Ulf Moeller, Bodo Moeller] |
57e7d3ce | 274 | |
deb2c1a1 DSH |
275 | *) Update Rijndael code to version 3.0 and change EVP AES ciphers to |
276 | handle the new API. Currently only ECB, CBC modes supported. Add new | |
277 | AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites | |
278 | for TLS" draft-ietf-tls-ciphersuite-03.txt. | |
279 | [Ben Laurie, Steve Henson] | |
280 | ||
9eea2be6 BM |
281 | *) In the NCONF_...-based implementations for CONF_... queries |
282 | (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using | |
283 | a temporary CONF structure with the data component set to NULL | |
284 | (which gives segmentation faults in lh_retrieve). | |
285 | Instead, use NULL for the CONF pointer in CONF_get_string and | |
286 | CONF_get_number (which may use environment variables) and directly | |
287 | return NULL from CONF_get_section. | |
288 | [Bodo Moeller] | |
289 | ||
741a9690 UM |
290 | *) Fix potential buffer overrun for EBCDIC. |
291 | [Ulf Moeller] | |
292 | ||
26e083cc DSH |
293 | *) New function OCSP_copy_nonce() to copy nonce value (if present) from |
294 | request to response. | |
295 | [Steve Henson] | |
296 | ||
02e4fbed DSH |
297 | *) Functions for OCSP responders. OCSP_request_onereq_count(), |
298 | OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() | |
299 | extract information from a certificate request. OCSP_response_create() | |
300 | creates a response and optionally adds a basic response structure. | |
301 | OCSP_basic_add1_status() adds a complete single response to a basic | |
302 | reponse and returns the OCSP_SINGLERESP structure just added (to allow | |
303 | extensions to be included for example). OCSP_basic_add1_cert() adds a | |
304 | certificate to a basic response and OCSP_basic_sign() signs a basic | |
305 | response with various flags. New helper functions ASN1_TIME_check() | |
306 | (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() | |
307 | (converts ASN1_TIME to GeneralizedTime). | |
308 | [Steve Henson] | |
309 | ||
88ce56f8 DSH |
310 | *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() |
311 | in a single operation. X509_get0_pubkey_bitstr() extracts the public_key | |
312 | structure from a certificate. X509_pubkey_digest() digests tha public_key | |
313 | contents: this is used in various key identifiers. | |
314 | [Steve Henson] | |
315 | ||
8cff6331 DSH |
316 | *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign |
317 | keyUsage if basicConstraints absent for a CA. | |
318 | [Steve Henson] | |
319 | ||
903872d6 RL |
320 | *) Make SMIME_write_PKCS7() write mail header values with a format that |
321 | is more generally accepted (no spaces before the semicolon), since | |
322 | some programs can't parse those values properly otherwise. Also make | |
323 | sure BIO's that break lines after each write do not create invalid | |
324 | headers. | |
325 | [Richard Levitte] | |
326 | ||
b8470240 DSH |
327 | *) Make sk_sort() tolerate a NULL argument. |
328 | [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] | |
329 | ||
50d51991 DSH |
330 | *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates |
331 | passed by the function are trusted implicitly. If any of them signed the | |
332 | reponse then it is assumed to be valid and is not verified. | |
333 | [Steve Henson] | |
334 | ||
a342cc5a DSH |
335 | *) Zero the premaster secret after deriving the master secret in |
336 | DH ciphersuites. | |
337 | [Steve Henson] | |
338 | ||
a43cf9fa DSH |
339 | *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT |
340 | to data. This was previously part of the PKCS7 ASN1 code. This | |
341 | was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. | |
342 | [Steve Henson, reported by Kenneth R. Robinette | |
343 | <support@securenetterm.com>] | |
344 | ||
345 | *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 | |
346 | routines: without these tracing memory leaks is very painful. | |
347 | Fix leaks in PKCS12 and PKCS7 routines. | |
348 | [Steve Henson] | |
349 | ||
75802000 UM |
350 | *) Fix for Irix with NO_ASM. |
351 | ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
352 | ||
ae0665b8 BM |
353 | *) Add some EVP_add_digest_alias registrations (as found in |
354 | OpenSSL_add_all_digests()), to SSL_library_init() | |
355 | aka OpenSSL_add_ssl_algorithms(). This provides improved | |
356 | compatibility with peers using X.509 certificates | |
357 | with unconventional AlgorithmIdentifier OIDs. | |
358 | [Bodo Moeller] | |
359 | ||
893b76c5 UM |
360 | *) ./config script fixes. |
361 | [Ulf Moeller, Richard Levitte] | |
362 | ||
ba8e2824 DSH |
363 | *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). |
364 | Previously it initialised the 'type' argument to V_ASN1_UTCTIME which | |
365 | effectively meant GeneralizedTime would never be used. Now it | |
366 | is initialised to -1 but X509_time_adj() now has to check the value | |
367 | and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or | |
368 | V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. | |
369 | [Steve Henson, reported by Kenneth R. Robinette | |
370 | <support@securenetterm.com>] | |
371 | ||
8e8972bb DSH |
372 | *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously |
373 | result in a zero length in the ASN1_INTEGER structure which was | |
374 | not consistent with the structure when d2i_ASN1_INTEGER() was used | |
375 | and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() | |
376 | to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() | |
377 | where it did not print out a minus for negative ASN1_INTEGER. | |
378 | [Steve Henson] | |
379 | ||
57108f0a BM |
380 | *) Fix 'openssl passwd -1'. |
381 | [Bodo Moeller] | |
382 | ||
73758d43 DSH |
383 | *) Add summary printout to ocsp utility. The various functions which |
384 | convert status values to strings have been renamed to: | |
385 | OCSP_response_status_str(), OCSP_cert_status_str() and | |
386 | OCSP_crl_reason_str() and are no longer static. New options | |
387 | to verify nonce values and to disable verification. OCSP response | |
388 | printout format cleaned up. | |
389 | [Steve Henson] | |
390 | ||
e8af92fc DSH |
391 | *) Add additional OCSP certificate checks. These are those specified |
392 | in RFC2560. This consists of two separate checks: the CA of the | |
393 | certificate being checked must either be the OCSP signer certificate | |
394 | or the issuer of the OCSP signer certificate. In the latter case the | |
395 | OCSP signer certificate must contain the OCSP signing extended key | |
396 | usage. This check is performed by attempting to match the OCSP | |
397 | signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash | |
398 | in the OCSP_CERTID structures of the response. | |
399 | [Steve Henson] | |
400 | ||
81f169e9 DSH |
401 | *) Initial OCSP certificate verification added to OCSP_basic_verify() |
402 | and related routines. This uses the standard OpenSSL certificate | |
403 | verify routines to perform initial checks (just CA validity) and | |
404 | to obtain the certificate chain. Then additional checks will be | |
405 | performed on the chain. Currently the root CA is checked to see | |
406 | if it is explicitly trusted for OCSP signing. This is used to set | |
407 | a root CA as a global signing root: that is any certificate that | |
408 | chains to that CA is an acceptable OCSP signing certificate. | |
409 | [Steve Henson] | |
410 | ||
dfebac32 BM |
411 | *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 |
412 | extensions from a separate configuration file. | |
413 | As when reading extensions from the main configuration file, | |
414 | the '-extensions ...' option may be used for specifying the | |
415 | section to use. | |
416 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
417 | ||
6308af19 DSH |
418 | *) Change PKCS12_key_gen_asc() so it can cope with non null |
419 | terminated strings whose length is passed in the passlen | |
420 | parameter, for example from PEM callbacks. This was done | |
421 | by adding an extra length parameter to asc2uni(). | |
422 | [Steve Henson, reported by <oddissey@samsung.co.kr>] | |
423 | ||
5782ceb2 DSH |
424 | *) New OCSP utility. Allows OCSP requests to be generated or |
425 | read. The request can be sent to a responder and the output | |
426 | parsed, outputed or printed in text form. Not complete yet: | |
427 | still needs to check the OCSP response validity. | |
428 | [Steve Henson] | |
429 | ||
c67cdb50 BM |
430 | *) New subcommands for 'openssl ca': |
431 | 'openssl ca -status <serial>' prints the status of the cert with | |
432 | the given serial number (according to the index file). | |
433 | 'openssl ca -updatedb' updates the expiry status of certificates | |
434 | in the index file. | |
435 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
436 | ||
d199858e BM |
437 | *) New '-newreq-nodes' command option to CA.pl. This is like |
438 | '-newreq', but calls 'openssl req' with the '-nodes' option | |
439 | so that the resulting key is not encrypted. | |
440 | [Damien Miller <djm@mindrot.org>] | |
441 | ||
10a2975a RL |
442 | *) New configuration for the GNU Hurd. |
443 | [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte] | |
444 | ||
9b4dc830 DSH |
445 | *) Initial code to implement OCSP basic response verify. This |
446 | is currently incomplete. Currently just finds the signer's | |
447 | certificate and verifies the signature on the response. | |
448 | [Steve Henson] | |
449 | ||
673b3fde BM |
450 | *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in |
451 | value of OPENSSLDIR. This is available via the new '-d' option | |
452 | to 'openssl version', and is also included in 'openssl version -a'. | |
453 | [Bodo Moeller] | |
454 | ||
c06648f7 BM |
455 | *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn |
456 | call failed, free the DSA structure. | |
457 | [Bodo Moeller] | |
458 | ||
a5435e8b BM |
459 | *) Allowing defining memory allocation callbacks that will be given |
460 | file name and line number information in additional arguments | |
461 | (a const char* and an int). The basic functionality remains, as | |
462 | well as the original possibility to just replace malloc(), | |
463 | realloc() and free() by functions that do not know about these | |
464 | additional arguments. To register and find out the current | |
465 | settings for extended allocation functions, the following | |
466 | functions are provided: | |
65a22e8e RL |
467 | |
468 | CRYPTO_set_mem_ex_functions | |
469 | CRYPTO_set_locked_mem_ex_functions | |
470 | CRYPTO_get_mem_ex_functions | |
471 | CRYPTO_get_locked_mem_ex_functions | |
472 | ||
a5435e8b BM |
473 | These work the same way as CRYPTO_set_mem_functions and friends. |
474 | CRYPTO_get_[locked_]mem_functions now writes 0 where such an | |
475 | extended allocation function is enabled. | |
476 | Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where | |
477 | a conventional allocation function is enabled. | |
478 | [Richard Levitte, Bodo Moeller] | |
65a22e8e | 479 | |
cbf0f45f DSH |
480 | *) Fix to uni2asc() to cope with zero length Unicode strings. |
481 | These are present in some PKCS#12 files. | |
482 | [Steve Henson] | |
483 | ||
3c914840 GT |
484 | *) Finish off removing the remaining LHASH function pointer casts. |
485 | There should no longer be any prototype-casting required when using | |
56a67adb GT |
486 | the LHASH abstraction, and any casts that remain are "bugs". See |
487 | the callback types and macros at the head of lhash.h for details | |
488 | (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). | |
3c914840 GT |
489 | [Geoff Thorpe] |
490 | ||
599c0353 LJ |
491 | *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. |
492 | If an EGD or PRNGD is running and enough entropy is returned, automatic | |
493 | seeding like with /dev/[u]random will be performed. | |
494 | Positions tried are: /etc/entropy, /var/run/egd-pool. | |
495 | [Lutz Jaenicke] | |
496 | ||
0c61e299 | 497 | *) Change the Unix RAND_poll() variant to be able to poll several |
361ef5f4 RL |
498 | random devices, as specified by DEVRANDOM, until a sufficient amount |
499 | of data has been collected. We spend at most 10 ms on each file | |
500 | (select timeout) and read in non-blocking mode. DEVRANDOM now | |
501 | defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" | |
502 | (previously it was just the string "/dev/urandom"), so on typical | |
503 | platforms the 10 ms delay will never occur. | |
504 | Also separate out the Unix variant to its own file, rand_unix.c. | |
505 | For VMS, there's a currently-empty rand_vms.c. | |
0c61e299 RL |
506 | [Richard Levitte] |
507 | ||
0b33bc65 DSH |
508 | *) Move OCSP client related routines to ocsp_cl.c. These |
509 | provide utility functions which an application needing | |
510 | to issue a request to an OCSP responder and analyse the | |
511 | response will typically need: as opposed to those which an | |
512 | OCSP responder itself would need which will be added later. | |
513 | ||
514 | OCSP_request_sign() signs an OCSP request with an API similar | |
515 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
516 | response. OCSP_response_get1_basic() extracts basic response | |
517 | from response. OCSP_resp_find_status(): finds and extracts status | |
518 | information from an OCSP_CERTID structure (which will be created | |
519 | when the request structure is built). These are built from lower | |
520 | level functions which work on OCSP_SINGLERESP structures but | |
521 | wont normally be used unless the application wishes to examine | |
522 | extensions in the OCSP response for example. | |
523 | ||
524 | Replace nonce routines with a pair of functions. | |
525 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
526 | generates a random value. OCSP_check_nonce() checks the | |
527 | validity of the nonce in an OCSP response. | |
528 | [Steve Henson] | |
529 | ||
530 | *) Change function OCSP_request_add() to OCSP_request_add0_id(). | |
8e961835 DSH |
531 | This doesn't copy the supplied OCSP_CERTID and avoids the |
532 | need to free up the newly created id. Change return type | |
533 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
534 | This can then be used to add extensions to the request. | |
535 | Deleted OCSP_request_new(), since most of its functionality | |
536 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
537 | clash) apart from the ability to set the request name which | |
538 | will be added elsewhere. | |
539 | [Steve Henson] | |
540 | ||
bf0d176e DSH |
541 | *) Update OCSP API. Remove obsolete extensions argument from |
542 | various functions. Extensions are now handled using the new | |
543 | OCSP extension code. New simple OCSP HTTP function which | |
544 | can be used to send requests and parse the response. | |
545 | [Steve Henson] | |
546 | ||
ec5add87 DSH |
547 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
548 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
549 | uses the special reorder version of SET OF to sort the attributes | |
550 | and reorder them to match the encoded order. This resolves a long | |
551 | standing problem: a verify on a PKCS7 structure just after signing | |
552 | it used to fail because the attribute order did not match the | |
553 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
554 | it uses the received order. This is necessary to tolerate some broken | |
555 | software that does not order SET OF. This is handled by encoding | |
556 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
557 | to produce the required SET OF. | |
558 | [Steve Henson] | |
559 | ||
a6574c21 RL |
560 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
561 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
562 | files to get correct declarations of the ASN.1 item variables. | |
563 | [Richard Levitte] | |
564 | ||
ecbe0781 DSH |
565 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
566 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
567 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
568 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
569 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
570 | ASN1_ITEM and no wrapper functions. | |
571 | [Steve Henson] | |
572 | ||
4e1209eb DSH |
573 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
574 | replace the old function pointer based I/O routines. Change most of | |
575 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
576 | [Steve Henson] | |
577 | ||
3f07fe09 RL |
578 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
579 | lines, recognice more "algorithms" that can be deselected, and make | |
580 | it complain about algorithm deselection that isn't recognised. | |
581 | [Richard Levitte] | |
582 | ||
78d3b819 | 583 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
584 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
585 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
586 | some old style ASN1 functions: this can be used to determine if old | |
587 | code will still work when these eventually go away. | |
09ab755c DSH |
588 | [Steve Henson] |
589 | ||
ec558b65 DSH |
590 | *) New extension functions for OCSP structures, these follow the |
591 | same conventions as certificates and CRLs. | |
592 | [Steve Henson] | |
593 | ||
57d2f217 DSH |
594 | *) New function X509V3_add1_i2d(). This automatically encodes and |
595 | adds an extension. Its behaviour can be customised with various | |
596 | flags to append, replace or delete. Various wrappers added for | |
597 | certifcates and CRLs. | |
598 | [Steve Henson] | |
599 | ||
5755cab4 DSH |
600 | *) Fix to avoid calling the underlying ASN1 print routine when |
601 | an extension cannot be parsed. Correct a typo in the | |
602 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
603 | [Steve Henson] | |
604 | ||
3880cd35 BM |
605 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
606 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
607 | when writing a 32767 byte record. | |
608 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
609 | ||
f640ee90 | 610 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 611 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
612 | |
613 | (RSA objects have a reference count access to which is protected | |
614 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |

9c67ab2f DSH |
619 | *) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
620 | entries for variables. | |
5755cab4 | 621 | [Steve Henson] |
9c67ab2f | 622 | |
1456d186 BM |
623 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
624 | [Bodo Moeller] | |
625 | ||
3ac82faa BM |
626 | *) Add functionality to apps/openssl.c for detecting locking |
627 | problems: As the program is single-threaded, all we have | |
628 | to do is register a locking callback using an array for | |
629 | storing which locks are currently held by the program. | |
3ac82faa BM |
630 | [Bodo Moeller] |
631 | ||
632 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
633 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
634 | ssl_verify_cert_chain() and thus can be called at any time | |
635 | during TLS/SSL handshakes so that thread-safety is essential. | |
636 | Unfortunately, the ex_data design is not at all suited | |
637 | for multi-threaded use, so it probably should be abolished. | |
638 | [Bodo Moeller] | |
639 | ||
2a86064f GT |
640 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. |
641 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |
642 | ||
2c15d426 DSH |
643 | *) Move common extension printing code to new function |
644 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
c08523d8 | 645 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |
2c15d426 DSH |
646 | [Steve Henson] |
647 | ||
de487514 DSH |
648 | *) New function X509_signature_print() to remove duplication in some |
649 | print routines. | |
650 | [Steve Henson] | |
651 | ||
06db4253 DSH |
652 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both |
653 | set (this was treated exactly the same as SET OF previously). This | |
654 | is used to reorder the STACK representing the structure to match the | |
655 | encoding. This will be used to get round a problem where a PKCS7 | |
656 | structure which was signed could not be verified because the STACK | |
657 | order did not reflect the encoded order. | |
658 | [Steve Henson] | |
659 | ||
36f554d4 DSH |
660 | *) Reimplement the OCSP ASN1 module using the new code. |
661 | [Steve Henson] | |
662 | ||
2aff7727 DSH |
663 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
664 | for its ASN1 operations. The old style function pointers still exist | |
665 | for now but they will eventually go away. | |
666 | [Steve Henson] | |
667 | ||
9d6b1ce6 | 668 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
669 | completely replaces the old ASN1 functionality with a table driven |
670 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
671 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
672 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
673 | has also been converted to the new form. | |
9d6b1ce6 DSH |
674 | [Steve Henson] |
675 | ||
8dea52fa BM |
676 | *) Change BN_mod_exp_recp so that negative moduli are tolerated |
677 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
678 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
679 | for negative moduli. | |
680 | [Bodo Moeller] | |
681 | ||
682 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
683 | of not touching the result's sign bit. | |
684 | [Bodo Moeller] | |
685 | ||
80d89e6a BM |
686 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
687 | set. | |
688 | [Bodo Moeller] | |
689 | ||
f1919c3d GT |
690 | *) Changed the LHASH code to use prototypes for callbacks, and created |
691 | macros to declare and implement thin (optionally static) functions | |
692 | that provide type-safety and avoid function pointer casting for the | |
693 | type-specific callbacks. | |
694 | [Geoff Thorpe] | |
695 | ||
1946cd8b UM |
696 | *) Use better test patterns in bntest. |
